Chanukah begins on the twenty-fifth day of the Jewish month of Kislev. The Jewish calendar is primarily based on the lunar cycle, and its dates fluctuate with respect to other calendar systems. Thus the first day of Chanukah can fall anywhere between November 28th and December 26th. Click here for an overview of the workings of the Jewish calendar.
